CATDOLL : CATDOLL: How to ferment cow dung to raise earthworms (video on how to ferment cow dung to raise earthworms)

1. How to use rabbit manure to breed earthworms? Can experts give me some advice?

If you only use rabbit manure to breed earthworms, the yield of earthworms will be very low. If you can collect a certain amount of pig manure, cow manure, or chicken manure and add them together to breed earthworms, the yield of earthworms will be high. In addition, the fermentation time of rabbit manure is long, which is more than 10 days longer than the fermentation time of manure.

How to breed earthworms

1. Planting seeds

After adjusting the humidity of the decomposed feed, spread it 10 cm along the trench dug in the mulberry garden, and then evenly put the eggs and young earthworms, and then put 5 cm of feed on it. The breeding density can be controlled at 2-2.5 kg/m2 or 10,000-15,000/m2. In principle, the density can be slightly higher in the early stage and gradually reduced in the later stage.

2. Shade and protection net

After the earthworm seeds are placed, a layer of plastic mosquito net is first covered on the ditch, and then plastic film, foam board and other rainproof materials are placed on it. This can prevent damage from rats, frogs, etc. and can also prevent rain and keep moisture.

3. Adjustment of temperature and humidity

The best breeding temperature for earthworms is 20-27℃, which is the same as the temperature requirement of silkworms.

In winter, the mulberry garden uses a thickened breeding bed to 40-50 cm, and the bait is covered with wheat straw or rice straw. The dead leaves of the mulberry trees and the cut mulberry branches can also be thickened and laid flat, and then covered with plastic cloth for heat preservation and moisture retention. In winter, when heating the greenhouse and silkworm room, it is necessary to pay attention to the smoke pipe of the stove.

To prevent maggots from getting gas poisoning, in addition, the relative humidity of the air should be maintained at 70%-80%, and ventilation should be carried out 3-4 times a day, 30 minutes each time. In summer, water once a day to cool down the plant in combination with ventilation. Generally, watering once a week is sufficient.

4. Frequent feeding

Remove earthworm castings, take out earthworm cocoons or turn over the feeding beds, and feed them 2-3 times a month, with a thickness of 10 cm each time. Keep the manure fresh and breathable to reduce the chance of earthworms becoming sick due to excessive accumulation of manure and untimely removal of earthworm castings, and create good conditions for the growth of earthworms.

5. Staged feeding

Earthworm breeding can be divided into seed group, breeding group and production group. Feed thinly and turn frequently. Feed twice a month, and the thickness of each feeding is 10 cm. Staged breeding is beneficial to the routine management of maggots, the reproduction and growth of earthworms, and the occurrence of diseases and insect pests.

6. Processing of earthworm cocoons and seeds

After 20 days of feeding, earthworms will produce a large number of cocoons through cross-breeding. At this time, the breeding earthworms and cocoons can be separated and hatched, and the separated cocoons, manure and earthworm manure mixture can be piled into a new breeding pile, maintaining good temperature and humidity.

When 50% of the earthworm cocoons are hatched, they can be covered with 10 cm of manure on the pile. They will be completely hatched in about 20 days. At this time, the density in the hatching pile is very high, and 50,000 to 60,000 cocoons can be hatched per 1 m2. They should be divided into piles in time and divided into 2-3 parts and covered with new manure for feeding. After routine management, they will all grow up in about 40 days.

The seeds separated from the breeding earthworms are re-mixed and fed with new manure. After 20 days, they can be bred again.

7. Harvest at the right time

The harvesting period of earthworms: Generally, it is carried out when the adult rings are obvious, the growth and development are slow, and the feed utilization rate is reduced. Harvest once a month in summer, and once every 1.5 months in spring and autumn, and replenish feed in time after harvesting.

2. How to raise earthworms using raw cow dung?

Technology of breeding earthworms with cow dung: breeding species, breeding methods, preference for warmth and humidity, fear of dryness, cocoon production, reproduction rate, feeding of bait, growth period, breeding density, and yield.

Breeding varieties: Good earthworm varieties can increase their annual growth rate by more than 200 times that of ordinary earthworms. They have good settlement, are heat-resistant and cold-resistant, and are suitable for production all year round. They have high yields of earthworm bodies and earthworm manure.

3. How to ferment cow dung to raise earthworms?

1. Feed preparation:

Fermentation: Use rice straw or stalks to spread a 10-15 cm thick layer of dry material, and then spread 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a spray bottle to spray water on each layer until the water seeps out. If garbage is used, pile up one layer of garbage and one layer of manure.

There is no limit to the length and width, and it should be covered tightly with a film. In the season with higher temperatures, it should be turned over every 7 days. Generally, the fermentation of the feed is completed after 3-5 times of turning over.

After the feed is fermented, test the pH value. Earthworm feed generally requires an appropriate pH value of 6-7.5, but the pH value of many animal and plant wastes is often higher or lower than this value.

When the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer; The scientific proportion of feed is the most effective way to increase the yield of cultured earthworms. 2. The above formula example requires:

① 50% cow dung, 50% pulp sludge;

② 100% cow dung or 100% mixture of all livestock dung;

③ 20% each of cow dung, pig dung, and chicken dung, and 40% of rice straw;

(Note: Chicken manure needs to be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will all escape or die.)

4. Do you need to add soil when raising earthworms using cow dung?

The best bait for earthworms is cow dung, pig dung, horse dung, sheep dung, rabbit dung, pig, sheep, rabbit dung mixed with straw and rice straw for fermentation, no need to add soil. 1. Feeding of bait: timely feeding of earthworms with sufficient bait is an important measure to ensure the rapid growth of earthworms. The bait is thrown in a pile with a thickness of 10 cm. Do not cover the bed surface completely and do not seek flatness to separate the earthworms.

2. Temperature for earthworm breeding: The best temperature is 15-25℃. In winter, use thickened breeding beds to 40-50 cm, cover the bait with straw, and then add plastic sheeting to keep warm and moisturize. In summer, try to water once a day to cool down. Stage breeding: It can be divided into seed groups, breeding groups, and production groups. Feed thinly and turn the beds frequently. Feed twice a month. Turn the beds before feeding. The thickness of each feeding is 10 cm. Keep the bait fresh and breathable at all times. Harvest in time: Harvest once a month in summer, and once every 1.5 months in spring and autumn. Replenish feed in time after harvesting. Rotation and update: The seed earthworms should be updated once a year, and the breeding beds should be replaced once a year to ensure the vigor of the earthworm population and prevent the decline of the earthworm population due to natural development.

Notes on raising earthworms: 1. Likes warmth: 15℃-25℃ is the best temperature. In order to create the best temperature, cover the greenhouse with plastic sheets in winter, cover with straw in summer, sprinkle water to cool down, hibernate at 0℃-5℃, freeze to death below 0℃, die above 40℃, and stop growing above 32℃. In Beijing, cover the greenhouse with plastic sheets on October 25th, and remove it on April 10th of the following year. In this way, the earthworms will grow to December 20th, and then to February 10th of the following year, they are basically dormant. From February, prevent the earthworms from escaping due to high temperature. Pay attention to uncover the plastic sheets in time after 10 days and gradually turn to the optimal temperature. At this time, pay special attention to the high temperature plastic sheets. This is the most difficult time. During the day, uncover the plastic sheet around the plant, cover it in the morning and evening, and water it in time to keep it moist. From March to June 10 is the peak period of spring spawning for earthworms. During the high temperature period, you should prevent heatstroke and cool down. It is best to water it once a day. From August 20 to June 10 to August 20 is the summer season, and the plant will gradually enter dormancy. At the end of September, it is the second peak period of spawning for earthworms.

2. Like moisture and afraid of dryness: The water content in the body of earthworms is about 80%, and the water content of bait is required to be 60%-80% (based on the water dripping from the fingers when holding the bait in the hand). Therefore, the moisture content of the breeding bed is required to be above 60%. In this way, water must be poured once a day or every 1-2 days. The water should not be too much, but it must be poured thoroughly and connected to the lower layer of material. The watering time is noon in winter, evening in summer, and daytime in spring and autumn.

3. Like darkness and afraid of light: earthworms hide during the day and come out at night. They can be seen foraging under the moonlight. The breeding bed should be covered with straw to keep it moist and shaded.

4. They like air and quietness. Loose bait is good for the growth of earthworms. Our experience over the years is to turn the bed over (about 20 cm thick) before feeding to increase ventilation. This is very important. Over the years, we have found that there are very few earthworms at the bottom of the bed soil, but there are still baits. The main reason is the lack of air, which is not good for the growth of earthworms.

5. How to breed earthworms with cow dung?

Cow dung is a good material for earthworm breeding. When using cow dung to breed earthworms, the cow dung selected must be fermented and dried. Feeding earthworms with such cow dung not only has good air permeability, but also will not ferment and burn the earthworms. Before feeding, the cow dung should be expanded with water, and then squeezed to remove excess water. When the cow dung can be held in a ball and a small amount of water can be squeezed out from the fingers (the relative water holding capacity is 70% at this time), it can be fed into the bed. The feed can be covered on the breeding bed in a full layer, and there is no need to worry about the earthworms being suffocated or burned.

Using cow dung to breed earthworms: First, the color is red, and the color is vermilion, which is bright and eye-catching. Second, the smell is fishy, ​​and the smell is unique and pungent. Third, the meat is firm, with less water content, and can withstand fish pecks. Fourth, it is small, like a matchstick, and of moderate size. Fifth, it is fresh and alive, hanging on the hook, swinging and tumbling. Another biggest advantage is that it grows and reproduces quickly. Under the conditions of a suitable temperature of 15-25℃ and a relative water holding capacity of 70%, the reproduction volume can be more than doubled in 15-20 days.

6. How to raise earthworms using cow dung?

When breeding earthworms with cow dung, the selected cow dung must be fermented and dried. Using such cow dung for autumn drinking not only has good air permeability, but also does not burn the earthworms during fermentation.

Before feeding, dry and fresh cow dung should be dispersed with water. Then squeeze out excess water. When the cow dung can be held in a ball and a small amount of water can be squeezed out from the fingers, the relative water holding capacity is 70%. It can be fed into the bed, and the feed can be covered on the feeding bed throughout the process. There is no need to worry about the earthworms being suffocated or burned. Cow dung is used to breed earthworms. First, the color is red, which is bright and eye-catching. Second, the smell is fishy, ​​which is unique and pungent.

The third is meat frying. It has low water content and can withstand fish pecks. The fourth is a small matchstick of moderate size.

The fifth is freshness. Hang it on the fish hook.

Another great benefit of rocking and tumbling is that it grows and reproduces quickly. Under the conditions of room temperature of 15-25 degrees and relative water holding capacity of 70/700, the mass of the three plants can be more than doubled in 15-20 days.

7. How to deal with dry cow dung to raise earthworms?

If you want to breed earthworms with cow dung, you need to ferment it. You can use Lebeifeng feces feed fermentation agent to ferment it. The fermentation method is very simple. Just mix the bacteria with cow dung evenly. If you want to breed earthworms, it is best to add some grass powder and straw powder. After mixing the raw materials, add water and pile them into a large pile for fermentation. Fermented cow dung breeding earthworms grow fast.

8. How to cultivate earthworms in wood ear bags?

Yes, but a certain amount of manure should be added for mixing. It is difficult to obtain an ideal breeding effect by using only edible fungus waste to breed earthworms because the raw materials are relatively simple and the nutrition is not very balanced.

In breeding, generally 70% of edible fungus waste can be added to 30% of pig and cow manure for mixed composting and fermentation, and then used for earthworm breeding.
